IT professionals who wish to earn the CCNP SP Operations certification should take the Maintaining Cisco Service Provider Quality of Service exam. The 642-785 exam is a 75 minute exam with 60-70 multiple choice questions. It is available only in English and must be taken at a Pearson VUE testing center.

QoS methodologies will be the basis of this exam. Candidates should be able to demonstrate support of Service Provider networking environments using QoS mechanisms, including implementing, monitoring, and troubleshooting in IOS and IOS XR operating systems. Candidates can take the Maintaining Cisco Service Provider Quality of Service (MSPQS) training course, which is offered exclusively for this exam, to prepare.

Before diving into technology-specific concepts and applications, all participants should have a solid understanding of QoS fundamentals, including fundamental technology, IOS software mechanisms, and issues that may result from implementation. Candidates must be able to manage performance using QoS statistics and troubleshoot in IP NGN NOC environments.

I Could Not Believe The Help I Got From These Study Guides

In the grand scheme of things, getting a study guide is not really that big of a deal. Many people use study guides every day. Of course, for me I have always scoffed at the idea of getting a study guide. They seemed to me only to be for the people who actually needed the help. I did not need any help because I was a true professional. To prove me wrong, my friend went to TestsForge and purchased the study information. I looked it over for my Cisco 642-785: Maintaining Cisco Service Provider Quality of Service and I could not believe what I was reading. They really helped me to understand the test a lot better. I passed without any difficulty with this help.
